Patterns that help you remember it

  • The last digits repeat in a cycle of 2: 5, 0.
  • Every answer ends in 0 or 5.
  • Split it into tens and ones: 155 × k = 150 × k + 5 × k.
  • Each answer is 155 more than the one before, so you can count on in steps of 155.

Building it from tables you already know

To multiply 155 by 9, multiply by 10 and take one 155 away: 1,550 − 155 = 1,395. To multiply by 11, multiply by 10 and add one more 155: 1,550 + 155 = 1,705. Multiplying by 4 is doubling twice: 155 → 310 → 620.

Every multiple of 155 is at least 155, so there are none below 100 and 6 below 1,000. A number is in the 155 times table exactly when it divides by 155 with no remainder.

Odd, even and the last digit

Because 155 is odd, the answers alternate between odd and even: 155 × 1 = 155 is odd, 155 × 2 = 310 is even, and so on. Multiplying by 10 always puts a zero on the end: 155 × 10 = 1,550, and 155 × 100 = 15,500. Multiplying by 5 is half of multiplying by 10: half of 1,550 is 775.

Using the 155 times table to divide

Every fact also works backwards: because 155 × 7 = 1,085, you know 1,085 ÷ 155 = 7 and 1,085 ÷ 7 = 155. Practising the table and its division facts together halves the work.

Questions

What is 155 × 12?

1,860.

What is half of 155 × 8?

155 × 8 = 1,240, and half of that is 620, which is 155 × 4. Halving one factor halves the answer.

What is 155 times 0?

0. Any number multiplied by zero is zero, because zero groups of 155 contain nothing.

What is 155 × 7 and 155 × 8?

155 × 7 = 1,085 and 155 × 8 = 1,240. These two are the facts most people find hardest, so they are worth practising on their own.
